Whether you choose Moss for its cool and lush appearance, Sedum for its succulent beauty, or Thyme for its aromatic foliage, these ground cover alternatives provide attractive, low-water options for sustainable landscaping.

Moss

Moss is an excellent choice as a low-water alternative to traditional grass. It thrives in shaded areas and retains moisture well, reducing the need for frequent watering. Regular misting or light watering is sufficient to maintain its lush green appearance.

Sedum 

Sedum, a type of succulent, offers outstanding drought tolerance and is an excellent option for water-efficient landscapes. It has thick, fleshy leaves that store water, allowing it to withstand dry conditions.

Once established, Sedum requires minimal maintenance. Occasional watering during prolonged dry spells is usually enough to keep it healthy. Sedum also benefits from light pruning to promote compact growth and maintain its shape.

Thyme

Thyme is another excellent option for a drought-tolerant ground cover. It offers both aesthetic appeal and water conservation benefits. Thyme is known for its aromatic foliage and beautiful flowers, adding color and fragrance to your lawn. It is highly tolerant of dry conditions and requires minimal watering once established.

Promote Drought Tolerance for a Healthy Lawn

Mow Minimally

Proper mowing height plays a significant role in promoting drought tolerance in your lawn. When you mow your grass too short, it puts stress on the plants and reduces their ability to withstand drought conditions. Opting for a higher mowing height allows the grass to develop deeper root systems, which help it access moisture from lower soil layers during dry periods.

To mow minimally and promote drought resistance, avoid cutting more than one-third of the grass blade’s length at a time. Removing too much of the grass blade stresses the plant and weakens its ability to withstand drought conditions.

Regularly sharpening your mower blades is also important. Dull blades can tear the grass rather than provide a clean cut, leaving it more susceptible to moisture loss and diseases. Clean cuts promote healthy growth and minimize stress on the grass blades, contributing to overall drought tolerance.

Leave Grass Clippings on the Turf

When you mow your lawn, the grass clippings that remain on the turf act as a natural mulch layer. This layer helps to reduce water evaporation from the soil surface, allowing the grassroots to retain more moisture. As a result, you can reduce the frequency of watering and conserve water resources.

Proper mulching techniques are essential to ensure that the grass clippings are distributed evenly across the lawn. This helps prevent clumping and promotes the decomposition of the clippings. To achieve effective mulching, use a mulching mower or attach a mulching kit to your regular mower. These tools finely chop the clippings into smaller pieces, allowing them to decompose more quickly and become incorporated into the soil.

Reduce Foot Traffic

Foot traffic can have a significant impact on the health and vitality of your lawn, especially during periods of drought. When the grass is stressed due to limited water availability, it becomes more vulnerable to damage caused by foot traffic.

If foot traffic on the lawn is unavoidable, try to schedule activities during cooler times of the day when the grass is less stressed. Avoid activities that involve heavy equipment or machinery, as they can cause significant damage to the lawn. Additionally, consider implementing aeration and overseeding practices to improve soil compaction and enhance the lawn’s ability to withstand foot traffic.

Aerate

Why is lawn aeration essential for enhancing drought tolerance? When soil becomes compacted over time, it restricts the movement of air, water, and nutrients to the grassroots. This compaction hinders the growth and development of the turf, making it more susceptible to drought stress.

Aeration involves creating small holes in the soil, allowing air, water, and nutrients to penetrate deeply into the root zone of the grass. This process offers numerous benefits, including improved root growth, enhanced water absorption, and increased overall lawn health.

Water Deeply

Instead of frequent shallow watering, which encourages shallow root growth, deep watering encourages the roots to reach deeper into the soil in search of moisture. This helps the grass become more resilient and better equipped to withstand periods of drought.

Aim to apply around 1 inch of water per week, including rainfall. This amount allows the moisture to penetrate the soil deeply, encouraging the roots to reach lower depths.

Let Your Lawn Go Dormant

During periods of prolonged drought, it may become necessary to allow your lawn to go dormant. When a lawn goes dormant, it enters a state of rest. The grass blades may turn brown or straw-like, and growth slows down significantly. This dormancy allows the grass to conserve water and energy by redirecting resources to the roots, which remain alive and active. A dormant lawn is not dead; it is simply conserving resources until conditions improve.

Factors to Consider When Choosing Drought-Tolerant Grass

Soil Considerations

When selecting drought-tolerant grass for your lawn, one crucial factor to consider is the type of soil in your yard. Different soil types have varying water-holding capacities and drainage characteristics, which can significantly impact a lawn’s ability to withstand drought conditions.

Sandy Soil

Sandy soil is well-draining but has a lower water-holding capacity. It tends to dry out quickly during droughts, making it challenging for grass to retain moisture. However, certain varieties of grass, such as Bermuda grass or Zoysia grass, can thrive in sandy soil due to their ability to tolerate drier conditions.

Clay Soil

Clay soil retains water well but has poor drainage, making it prone to waterlogging during heavy rains. During droughts, clay soil becomes compacted and hard, restricting water penetration. Choosing grass varieties like Tall Fescue or Buffalo grass, which have good drought tolerance and can adapt to clay soil, is beneficial.

Loam Soil

Loam soil is considered the ideal soil type for lawns. It has a balanced mixture of sand, silt, and clay, providing good drainage while retaining adequate moisture. Many grass species, including Kentucky Bluegrass and Perennial Ryegrass, perform well in loam soil and exhibit good drought tolerance.

Sun Exposure

Different grass species have varying sunlight requirements, and matching the grass type with the specific sun exposure conditions will contribute to its overall resilience during periods of drought. 

Full Sun

If your lawn receives ample sunlight throughout the day, consider grass varieties like Bermuda grass, St. Augustine grass, or Zoysia grass. These grasses are well-suited for full sun exposure, as they have good heat and drought tolerance.

Partial Shade

For areas with moderate shade or filtered sunlight, select grass varieties such as Fine Fescue, Tall Fescue, or Centipede grass. These grasses can tolerate some shade while still maintaining their drought-resistant qualities.

Full Shade

In heavily shaded areas where direct sunlight is limited, opt for shade-tolerant grass varieties like Creeping Red Fescue or Shade-tolerant Ryegrass. These grasses have adapted to lower light conditions and can still exhibit good drought tolerance.
